Deep endometriosis of right ureter

This code signifies the presence of endometrial tissue deeply infiltrating the wall of the right ureter. This condition can lead to ureteral obstruction, hydronephrosis, and renal dysfunction if left untreated. It is a specific manifestation of endometriosis affecting the urinary tract.

Use this code when documentation explicitly states deep endometriosis involving the right ureter. This diagnosis is typically confirmed through imaging studies (e.g., MRI, CT) or surgical findings during laparoscopy or laparotomy. Supporting documentation should detail the location and depth of the endometrial implants.

• Differentiate from superficial endometriosis of the ureter, which would be coded differently.
• Ensure laterality (right) is clearly documented; separate codes exist for left or bilateral involvement.
• Consider sequencing with codes for associated complications like hydronephrosis or renal failure, if present.
